Amazon Cuts Some M3 Compute Instances 10%

Amazon has reduced prices 10% on two commonly used compute instance types: the M3 extra-large and M3 double-extra-large virtual machines. At the same time, it's launched a new instance type good for processing 3-D graphics.

The price reductions take effect Nov. 1 and apply to M3 extra-large instances, which drop from $.50 to $.45 an hour, while the double-extra-large instances go from $1 to $.90 an hour. The instance type is a general-purpose one often used with small and mid-size databases, SAP applications, Microsoft SharePoint and video encoding.

Many Amazon price cuts have been applied to offerings in the highly competitive cloud storage arena. Others have promoted new services or fringe services. Tuesday's cut applies to one of Amazon's core, mainstream compute offerings.

Jeff Barr, AWS cloud evangelist, posted a brief notice of the price cut on the Amazon Web Services blog, then issued a tweet about the price reduction. AWS CTO Werner Vogels repeated the tweet to his broad following to make sure the word got out.

The reduction applies to all Amazon regions. The pricing applies to Amazon's U.S. East 1 region in Ashburn, Va. The price cut applies to both on-demand and reserved instances.

The M3 has significantly more memory and CPU power than an M1 small, which featured a virtual CPU equivalent to one EC2 compute unit (ECU), which equals a 2007 Intel Xeon or AMD Opteron running at 1 to 1.2 GHz. The M3 extra-large instance is assigned 15 GB of memory, compared to the 1.7 GB of an M1. The four virtual CPUs assigned to an M3 are the equivalent of 13 EC2 compute units. When it comes to M3 double extra-large, the memory rises to 30 GBs and 26 EC2 compute units.

In Amazon's somewhat convoluted lexicon, an M3 instance is a second-generation M1 instance. Its virtual CPU with 13 to 26 EC2 compute units represents one or more recently issued Intel Xeon E5-2670 processors. As one generation of chips follows another, translating the hardware into EC2 compute units gets trickier for those outside of Amazon, but AWS posts a chart of assigned ECU values on its website.

Amazon also announced on Tuesday that it is offering a new instance type good for processing 3-D graphics. The G2 instance runs on a high-performance Nvidia Grid graphical processing unit with 1,536 parallel processing cores. It is designed to be used for video creation services, 3-D visualizations and stream graphics-intensive applications, Amazon spokesmen said.

Enterprise cloud adoption has evolved to the point where hybrid public/private cloud designs and use of multiple providers is common. Who among us has mastered provisioning resources in different clouds; allocating the right resources to each application; assigning applications to the "best" cloud provider based on performance or reliability requirements.
